Product Details

The Manley 11178-12 is a high-performance Race Flo intake valve engineered specifically for Nissan Patrol engines. This professional-grade valve features a 40.5mm head diameter and is part of Manley's renowned Race Series, designed to meet the demanding requirements of bracket racing, drag racing, and oval track applications operating below 8000 RPM.

Key Features:

  • NK-842 stainless steel construction for exceptional durability and heat resistance
  • Race Flo design with necked-down stem in the port area for enhanced airflow and reduced weight
  • Chrome-plated valve stems with .0002" thick hard coating for superior wear resistance
  • Hardened valve tips that resist erosion better than traditional stellite tipping
  • Swirl polished underhead areas and fully machined combustion faces for optimized flow
  • 40.5mm intake valve head diameter engineered for Nissan Patrol applications

Manley's Race Series valves utilize premium materials and precision manufacturing to deliver performance that meets or exceeds the industry's highest standards. The Race Flo design features Manley's original Pro-Flo stem profile, which reduces the stem diameter in the fillet area to increase airflow while decreasing valve weight. This valve is an excellent upgrade for performance builds and represents superior quality at a competitive price point compared to alternatives.
